LEE,MATTHEW R; CASTILLA,JUAN CARLOS; FERNÁNDEZ,MIRIAM; CLARKE,MARCELA; GONZÁLEZ,CATHERINE; HERMOSILLA,CONSUELO; PRADO,LUIS; ROZBACZYLO,NICOLAS; VALDOVINOS,CLAUDIO.
A comprehensive literature review was conducted to determine the species richness of all the possible taxa of free-living benthic marine invertebrates in Chile. In addition, the extent of endemism to the Pacific Islands and deep-sea, the number of non-indigenous species, and the contribution that the Chilean benthic marine invertebrate fauna makes to the world benthic marine invertebrate fauna was examined. A total of 4,553 species were found. The most speciose taxa were the Crustacea, Mollusca and Polychaeta. Species richness data was not available for a number of taxa, despite evidence that these taxa are present in the Chilean benthos. The Chilean marine invertebrate benthic fauna constitutes 2.47 % of the world marine invertebrate benthic fauna. There...

Geographic variation in diversity of wave exposed rocky intertidal communities along central Chile RChHN
BROITMAN,BERNARDO R; VÉLIZ,FREDY; MANZUR,TATIANA; WIETERS,EVIE A; RANDALL FINKE,G; FORNES,PAULINA A; VALDIVIA,NELSON; NAVARRETE,SERGIO A.
Along the coast of central Chile, geographic trends of diversity have been inferred from literature compilations and museum collections based on species range limits for some taxonomic groups. However, spatially-intensive field-based assessments of macrobenthic species richness are largely missing. Over the course of a multiyear study (1998-2005), we characterized latitudinal patterns of rocky intertidal diversity at 18 sites along the coast of central Chile (29-36° S). At each site, the number of sessile and mobile macrobenthic species was quantified in 0.25 m² quadrats. Two estimators of local (alpha) diversity were used: observed local species richness, calculated from the asymptote of a species-rarefaction curve, and the Chao2 index, which takes into...

Influence of pitfall designs and use of baits on the capture of small mammals in Southern Minas Gerais, Brazil - doi: 10.4025/actascibiolsci.v35i4.17498 Biological Sciences
Rocha, Daniel Gomes da; Instituto de Desenvolvimento Sustentável Mamirauá / Instituto Nacional de Pesquisas da Amazônia; Passamani, Marcelo; Universidade Federal de Lavras.
Each kind of trap tends to be selective on species sampled, in a way that each one only reveals part of the abundance and species richness of the community sampled. In this way, in order to know the factors that affect the success of sampling methods is crucial for a better planning of experiments and data analysis. The aim of this study was to evaluate the factors that affect the success of pitfall traps in capturing small mammals, such as trap size, designs and use of bait. The study was carried out in two reserves inside the campus of the Universidade Federal de Lavras (UFLA), in South Minas Gerais State, Brazil. In total, 65 specimens belonging to 8 species were caught. Different types of trap design (Y-shaped and I-shaped) have not influenced the...

Large and medium-sized mammals from Chandless State Park, Acre, Brazil. Mastozool. neotrop.
Borges,Luiz H. M; Calouro,Armando M; de Sousa,Jesus R. D.
The Neotropical region hosts the greatest diversity of mammals in the world. Western Amazonia, where the State of Acre is located, harbors one of the highest mammalian species diversity in the Neotropics. Mammals are considered important biodiversity components and play a key role in regulating and structuring forest ecosystems. However, there are considerable knowledge gaps regarding species distribution and rich­ness in the Amazon region. This study aims at documenting the medium and large-sized mammal species in Chandless State Park (PEC - Parque Estadual Chandless) giving special attention to those classified as rare or threatened. Four different methods were used in two years of research, 2008 and 2013: linear transect, camera trap, interviews and...

Les virus de l'estuaire de la Charente el du bassin de Marennes-Oleron. Dynamiques spatio-temporelles et interactions avec les communautés bactériennes ArchiMer
Auguet, Jean-christophe.
This study is divided in two parts; one aim is to evaluate the in situ spalio-temporal dynamics of viral communities in the Charante estuary in order to define the appropriate seasons to conduct in vitro viral enrichment experiments. These experiments, that constitute the second part of this study, were performed to assess the impact of freshwater viruses carried by the Charante River on the dynamics and composition of coastal bacterial communities. With abundance ranging from 1.4 x 107 to 208 x I07 VLPml-1. viruses are the most abundant component among plankton microorganisms in surface waters of the Charente estuary. Thre temporal dynamics of this component reflects the indirect influence of temperature through the control of bacterial abundance,...

Low predictive power of mid-domain effect to explain geographic species richness patterns in Palearctic songbirds Naturalis
Aliabadian, M.; Roselaar, C.S.; Sluys, R.; Nijman, V..
In the study of diversity patterns, the Mid-domain effect (MDE), which explains gradients in diversity solely on the basis of geometric constraints, has emerged as a null-model against which other hypotheses can be tested. The effectiveness, measured by its predictive power, of these MDE models appears to depend on the size of the study area and the range-sizes of the taxa considered. Here we test the predictive power of MDE on the species richness patterns of birds and assess its effectiveness for a variety of species range sizes. We digitised distribution maps of 889 species of songbird endemic to the Palearctic, and analysed the emergent biogeographic patterns with WORLDMAP software. MDE had a predictive power of 20% when all songbirds were included....

Mammal and butterfly species richness in Chile: taxonomic covariation and history RChHN
SAMANIEGO,HORACIO; MARQUET,PABLO A.
Understanding species richness spatial distribution is of fundamental importance to face the current biodiversity crisis that affects biotas around the world. Taxonomical covariation in species occurrence may offer the possibility to identify common factors that restrict species richness, as well as some guidelines to the identification of key areas for conservation purposes. To this aim, we analyze the geographic distribution of mammals and butterflies in Chile using 0.5° latitude and longitude quadrats. We found that, for both taxa, there is a strong bell-shaped latitudinal gradient in species richness with a peak at mid-latitudes (33-43° S). The results from multiple stepwise regression analysis shows that for both taxa productivity measured using the...

Mapping diversity indices: not a trivial issue ArchiMer
Granger, Victoria; Bez, Nicolas; Fromentin, Jean-marc; Meynard, Christine; Jadaud, Angelique; Merigot, Bastien.
Mapping diversity indices, that is estimating values in all locations of a given area from some sampled locations, is central to numerous research and applied fields in ecology. Two approaches are used to map diversity indices without including abiotic or biotic variables: (i) the indirect approach, which consists in estimating each individual species distribution over the area, then stacking the distributions of all species to estimate and map a posteriori the diversity index, (ii) the direct approach, which relies on computing a diversity index in each sampled locations and then to interpolate these values to all locations of the studied area for mapping. For both approaches, we document drawbacks from theoretical and practical viewpoints and argue...

Mesophotic mushroom coral records at Brunei Darussalam support westward extension of the Coral Triangle to the South China Sea waters of Northwest Borneo Naturalis
Lane, D.J.W.; Hoeksema, B.W..
This communication reports the discovery of two additional fungiid coral species, Cycloseris hexagonalis and Lithophyllon spinifer, from a relatively deep shelf reef in Brunei waters. These new records plus two earlier excluded ones, Cycloseris explanulata and C. wellsi, raise the known number of mushroom coral species at this Northwest Borneo location to 37 which is comparable to the number (n=35) reported for reefs of the nearby Tungku Abdul Rahman Park/Kota Kinabalu area, outside but close to the currently recognized northwest boundary of the zone of maximum marine biodiversity, the Coral Triangle (CT). The fungiid species richness at Brunei is compared with those of other sites in this eastern part of the South China Sea (SCS), and the adjacent...

Patterns in species richness and composition of plant families in the Malay Archipelago Naturalis
Welzen, P.C. van; Slik, J.W.F..
Distribution patterns or the recognition of phytogeographical areas is usually based on the presence and absence of species. The taxa on which the analyses are based remain virtually anonymous. Here we want to determine which Malesian plant families (within the sample) are responsible for species richness and composition patterns. The other aim is to determine whether the different islands groups in Southeast Asia can be grouped into separate phytogeographical areas. A Principal Coordinates Analysis (PCO) showed the presence of three phytogeographical areas within Malesia: The Sunda Shelf (Malay Peninsula, Sumatra, Borneo) in the west, the Sahul Shelf (New Guinea) in the east, and all remaining central areas forming Wallacea. The latter can be divided into...

Plant diversity and galling arthropod diversity searching for taxonomic patterns in an animal-plant interaction in the Neotropics Boletín de la Sociedad
de Souza Mendonça, Jr.,Milton.
Gall-inducers are a special guild of endophytic herbivores generating distinct structures known as galls. Gallers are species-specific, as the galls they induce: each gall morphotype is unique. The relationship between plants and gallers is close, and some of the hypotheses to explain galling diversity consider plants directly; others do not. Here I review current diversity hypotheses on galls and their hosts, adding ideas on the interpretation of galler host plant data. The example comes from an ongoing standardised inventory of galls and hosts in Rio Grande do Sul (RS) state, southern Brazil. The questions addressed here are whether: a) galls occur consistently on some plant taxa in different areas, b) these taxa are important for vegetation composition,...

Range of Variability in Southern Coastal Plain Forests: Its Historical, Contemporary, and Future Role in Sustaining Biodiversity Ecology and Society
Mitchell, Robert J.; Jones Ecological Research Center; Robert.Mitchell@jonesctr.org; Duncan, Sally L.; Oregon State University; Sally.Duncan@oregonstate.edu.
Historical range of variation (HRV) has been used as a conceptual tool to determine appropriate management actions to sustain or restore diversity of ecological systems. This concept has come into question for both biological and social considerations, and the southeastern United States is a good model system to test its utility. Southeastern Coastal Plain upland pine savannas and woodlands and their associated wetlands are among the most diverse communities in temperate North America, having both high levels of species richness and large numbers of endemic flora and fauna. However, this diversity is intimately linked with disturbance regimes. Maintaining frequent fire, varied in season based on changing management objectives through time, is the most...

This study aims to describe the patterns of soft bottom macrozoobenthic richness along French coasts. It is based on a collaborative database developed by the “Réseau des Stations et Observatoires Marins” (RESOMAR). We investigated patterns of species richness in sublittoral soft bottom habitats (EUNIS level 3) at two different spatial scales: 1) seaboards: English Channel, Bay of Biscay and Mediterranean Sea and 2) 0.5° latitudinal and longitudinal grid. Total observed richness, rarefaction curves and three incidence-based richness estimators (Chao2, ICE and Jacknife1) were used to compare soft bottom habitats species richness in each seaboard. Overall, the Mediterranean Sea has the highest richness and despite higher sampling effort, the English Channel...

Although wildfire plays an important role in maintaining biodiversity in many ecosystems, fire management to protect human assets is often carried out by different agencies than those tasked for conserving biodiversity. In fact, fire risk reduction and biodiversity conservation are often viewed as competing objectives. Here we explored the role of management through private land conservation and asked whether we could identify private land acquisition strategies that fulfill the mutual objectives of biodiversity conservation and fire risk reduction, or whether the maximization of one objective comes at a detriment to the other. Using a fixed budget and number of homes slated for development, we simulated 20 years of housing growth under alternative...

Spatial pattern in species richness of demersal fish assemblages on the continental shelf of the northern Mediterranean Sea: a multiscale analysis ArchiMer
Gaertner, J; Bertrand, Jacques; Relini, G; Papaconstantinou, C; Mazouni, N; De Sola, L; Durbec, J; Jukic Peladic, S; Souplet, Arnauld.
The species richness pattern of groundfish species in the entire northern Mediterranean Sea was examined at 3 spatial scales: region, large biogeographical zone and basin. We analysed 1914 trawl hauls collected using a single sampling design in the trawlable areas of the continental shelves between the Strait of Gibraltar and the Strait of Dardanelles (from 36.3 to 45.7 degrees N and 5.3 degrees W to 28 E). Spatial pattern in species diversity was assessed using complementary methods (Chao2 estimates of total species richness, mean species richness and beta diversity). No matter which scale was used, the expected longitudinally decreasing trend in species richness, which has been widely described in previous studies, did not appear when comparing estimates...

Species composition of testate amoebae in Lake Monte Alegre, Ribeirão Preto, SP, Brazil Biological Sciences
Mousinho, Lucas Pessanha; Silva, Mariana Lessa Carneiro da; Arrieira, Rodrigo Leite; Schwind, Leilane Talita Fatoreto.
We aimed to perform the first survey of testate amoebae community composition in Lake Monte Alegre at São Paulo state, and contribute to mitigate the taxonomic impediment regarding the diversity of testate amoebae in Brazil. Samplings were performed in 20 sampling sites within the lake, in the limnetic and littoral regions in April 2015, using a 58 µm-meshplankton net. We identified 20 taxa of testate amoebae belonging to four families: Arcellidae (8 taxa), Centropyxidae (4 taxa), Difflugiidae (7 taxa) and Lesquereusiidae (2 taxa). The littoral region showed the highest number of taxa (n = 20), whereas in the limnetic region 11 taxa were registered. Therefore, our results evidenced the importance of testate amoebae in aquatic systems, and that further...
